JP 2008-206131 A

  However, if video data and character data (data broadcasting) are separated and video data is displayed on half of one display screen and character data is displayed on the other half, both video data and character data will be small. It ’s hard to see.

  An object of the present invention is to display video data on one display screen of an electronic device having a plurality of display screens, and display character data (data broadcast) associated with the video data on the other display screen. It is to provide an electronic device capable of improving the performance.

In order to solve the above problems, an electronic device according to the present invention includes:
A first display screen capable of displaying information;
A second display screen capable of displaying information;
A coupling mechanism for movably coupling the first display screen and the second display screen, and the second display screen is moved to a position where the second display screen is visible and a position where the second display screen is not visible relative to the first display screen. A possible coupling mechanism;
A display control unit for controlling display of information on the first display screen and the second display screen,
A position detection unit that detects whether the second display screen is in a visible position or in an invisible position with respect to the first display screen;
A data receiver capable of receiving the first data and the second data associated with the first data;
In an electronic device comprising
A data separator that separates the first data and the second data received by the data receiver;
The display control unit displays the first data and the second data on the first display screen in a state where the position detection unit detects that the second display screen is in an invisible position. When the unit detects that the second display screen is in a visible position, the first data separated by the data separation unit is displayed on the first display screen, and the second data is displayed on the second display screen. To do.

  According to the electronic device of the present invention, in the state where the second display screen is invisible with respect to the first display screen, only the first data or both the first data and the second data are displayed on the first display screen. And when the second display screen is in a position where the second display screen is visible with respect to the first display screen, the first data is displayed on the first display screen and the second data is displayed on the second display screen. it can. Accordingly, the first data can be displayed in a large size on the first display screen, and the second data can be displayed in a large size on the second display screen, so that visibility can be enhanced as much as possible.

  As a specific embodiment, when the moving image data included in the terrestrial digital broadcasting data such as 1Seg is the first data and the character data (data broadcasting) associated with the moving image data is the second data, the second screen is displayed by a user operation. When visual recognition becomes possible from an invisible state, moving image data can be displayed on the first display screen and character data (data broadcast) can be displayed on the second display screen. Thereby, since moving image data and character data (data broadcasting) can be displayed largely on the first display screen and the second display screen, respectively, visibility can be improved.

  Further, the trigger for switching the display is the position of the second display screen with respect to the first display screen. Thereby, for example, when the user wants to display the second data in a large size, the display can be switched by simply moving the second display screen relative to the first display screen so that the second display screen is visible. It is easy to operate.

Embodiments of the present invention will be described below with reference to the drawings.
1 to 6 are diagrams showing an example of the structure of the electronic device (10) according to the present embodiment.
As this electronic device (10), for example, a portable electronic device having a reception function of digital terrestrial broadcasting can be exemplified. In the following embodiments, data received by the electronic device (10) is terrestrial digital broadcast data, and the moving image data included in the broadcast data is the first data and character data (data broadcast) associated with the moving image data. Is described as the second data.

  As shown in FIG. 8, the terrestrial digital broadcast data has moving image data and character data (data broadcasting) associated with the moving image data. The character data is data described in a markup language such as BML (Broadcast Markup Language). As a specific example of this data, for example, when the movie data is a movie movie representing a sport movie such as baseball, data representing a game progress scoreboard, information on participating players, and the like.

  As shown in FIGS. 1 to 6, the electronic device (10) includes a display screen (21) (31) capable of displaying various information such as characters, figures, still images, and moving images, and a surface of the display screen. The display units (20) and (30) having touch panels (22) and (32) that can be operated by touching by the user are connected and configured to be movable by opening and closing, sliding, and the like by a connecting mechanism (40). be able to.

  1 to 6 show a state in which the electronic device (10) is horizontally arranged so that the second display screen (31) faces upward, and the second display screen (31) in FIG. 1 to 4, the front left is “front”, the rear right is “rear”, and the left side in FIG. 5 and FIG. The front side and the right side are called “rear”. “Left” and “right” mean the left and right directions viewed from the “front” direction, respectively. Further, regarding the first display unit (20) and the second display unit (30), the front end portion shown in FIG. 1 is referred to as a “base end”, and the rear end portion is referred to as a “rear end”. The display part located is called the first display part (20), and the display part located on the front side is called the second display part (30).

  As shown in the drawing, each of the first display unit (20) and the second display unit (30) is provided with a display screen (23) (33) on one surface, that is, an upper surface in FIG. 21) (31) is accommodated so as to be visible from the opening side. The display screens (21) and (31) are electro-optical devices such as a liquid crystal display, for example. The display screens (21) and (31) are electrically connected to a control means (60) and a display control section (70) (see FIG. 7) described later, and are displayed by the control means (60) and the display control section (70). Various information is displayed under control.

  Touch panels (22) and (32) are provided on the opening sides of the display screens (21) and (31). The touch panels (22) and (32) are disposed so as to close the openings of the housings (23) and (33), and are formed to be transparent so that the display screens (21) and (31) are visible. Examples of the touch panels (22) and (32) include those of a capacitance type and a resistance film type. The touch panels (22) and (32) are electrically connected to the control means (60) (see FIG. 7) via the touch panel controllers (25) and (35). When the user touches and operates the touch panel (22) (32) with a finger or the like, coordinate information indicating the position touched with the fingertip or the like is delivered to the control means (60) via the touch panel control units (25) and (35). Thereby, the user's operation content is transmitted to the control means (60).

  As a user operation using the touch panel (22) (32), a tap or double tap that touches the touch panel (22) (32) is relatively short, and the touch time of the touch panel (22) (32) is longer than these. (22) So-called flick, touch panel (22) which touches the touch panel (22) (32) with a finger or stylus, etc., and then pays quickly after moving the touch point while touching (32) Examples include so-called pinch that changes the distance while touching (32) with two fingers or the like, and so-called long touch in which the same position on the touch panel (22) (32) is pressed long.

  The first display unit (20) and the second display unit (30) are relatively movable by the coupling mechanism (40). In the electronic device (10) of the present embodiment, FIGS. As shown, the first display section (20) is slidable and rotatable with respect to the second display section (30).

  As shown in FIGS. 1 to 6, the connection mechanism (40) connects the front-rear direction approximate center on the back side of the first housing (23) and the tip of the second housing (33). The connection mechanism (40) can be constituted by a plurality of arms and the like, and the description thereof will be omitted. However, as will be described later, the connection mechanism (40) causes the first display unit (20) to be second. The display unit (30) is slidable and rotatable in the approaching and separating directions. The connecting mechanism (40) may be configured to connect the first display unit (20) and the second display unit (30) only to slide or only to rotate.

  The relative position of the first display section (20) with respect to the second display section (30) can be detected by the position detection means (80). The position detection means (80) of the present embodiment can be exemplified by a membrane switch (82) provided at the lower left corner of the upper surface of the second display section (30), and the signal value varies depending on whether the membrane switch (82) is on or off. A relative position signal, which is a binary signal to be switched, is output to the control means (60). When the first display unit (20) is superimposed on the second display unit (30) and the second display screen (31) is hidden behind the first display unit (20) and cannot be seen, the membrane switch (82) Is pressed by the back surface of the first display section (20) and turned on, and a relative position signal having a signal value of “1” is output from the position detection means (80) to the control means (60).

  On the other hand, when the first display unit (20) and the second display unit (30) are relatively moved so that the second display screen (31) is visible, the second display screen (31) is displayed. Is visible, and the membrane switch (82) is turned off, and a relative position signal having a signal value of “0” is output from the position detection means (80) to the control means (60).

  Thus, in the present embodiment, by referring to the signal value of the relative position signal output from the position detection means (80), the position where the first display screen (21) overlaps the second display screen (31), That is, it is possible to detect whether the second display screen (31) is in a position where it cannot be visually recognized or in a position where it can be visually recognized.

In this embodiment, a membrane switch (82) for detecting the relative position of the second display screen (31) with respect to the first display screen (21) is provided at the corner of the upper surface of the second display section (30). The position is not particularly limited. Further, the position detecting means (80) may be constituted by a non-contact type sensor composed of a magnet and a magnet sensor. For example, either the magnet or the magnet sensor is set to the first display unit (20), and the other is set to the second display so that the first display unit (20) is opposed to the second display unit (30). The relative position between the first display screen (21) and the second display screen (31) can also be determined based on the signal output from the magnet sensor provided in the section (30).
Further, a potentiometer (84) for detecting a relative angle change between the first display unit (21) and the second display unit (31) or both display units (21) (31) and the coupling mechanism (40) is arranged. Thus, the position detection means (80) may be configured (see FIG. 5 (a)).

FIG. 7 shows an example of a block diagram of the electronic apparatus of the present invention.
All control of the electrical equipment is performed by control means (60) composed of a CPU or the like. The control means (60) is electrically connected to the first display screen (21) and the second display screen (31) described above. A display control unit (70) is electrically connected to the control means (60), and performs display control of various information on each of the first display screen (21) and the second display screen (31).

  The first touch panel (22) and the second touch panel (32) are electrically connected to the control means (60) via the first touch panel control unit (25) and the second touch panel control unit (35), respectively. The user input from the first touch panel (22) and the second touch panel (32) is transmitted to the control means (60) via the touch panel control units (25) and (35), and the control means (60) In response to the input, the information on the display screens (21) and (31) can be edited and operated.

  The control means (60) also includes a memory (not shown) for storing various operations of the electronic device (10) and various data desired by the user, and data reception for receiving terrestrial digital broadcast data (see FIG. 8). The part (72) and the like are electrically connected. The data receiving unit (72) includes, for example, an antenna and a demodulation circuit, receives terrestrial digital broadcast data distributed via a mobile packet communication network or the like, and delivers it to the control means (60).

  The terrestrial digital broadcast data (see FIG. 8) received by the data receiving unit (72) is converted into the moving image data (first data) by the data separating unit (74) electrically connected to the control means (60). It is separated into character data (second data / data broadcast) associated with the moving image data.

  The control means (60) executes an operation of executing processing according to various instructions input via the first touch panel (22) and the second touch panel (32). For example, when receiving an instruction to receive terrestrial digital broadcast data and display a moving image represented by the moving image data included in the terrestrial digital broadcast data via the first touch panel (22) or the second touch panel (32), the control means ( 60) receives the terrestrial digital broadcast data by the data receiving unit (72), and displays the moving image represented by the moving image data included in the terrestrial digital broadcast data by the display control unit (70). This will be described later with reference to the flowchart of FIG.

  The 1st display part (20) and the 2nd display part (30) which were connected by the above-mentioned connection mechanism (40) are relatively movable in the following ways.

  For example, in FIG. 1, the first display unit (20) and the second display unit (30) have the first display screen (21) and the second display screen (31) substantially in the same plane, and the first casing (23 ) And the distal end of the second housing (33) are close to each other. The side view of FIG. 1 is FIG. This state is referred to as a “flat approach state”. In the flat approaching state, the first display screen (21) and the second display screen (31) are continuous and visible as one screen, and the first touch panel (22) and the second touch panel (32) are also continuous 1 It can be operated like two touch panels. In the flat approaching state, the membrane switch (82) is not pressed by the back surface of the first display unit (20) and is in an off state. Therefore, in the flat approaching state, the position detection means (80) gives a relative position signal having a signal value of “0” to the control means (60).

  From the above flat approach state, as shown in FIG. 2, the user supports the back of the second housing (33) with the four fingers of the hand (P) and supports the second touch panel (32) with the thumb ball while holding both thumbs When the first touch panel (22) is pushed backward in (T), the first display unit (20) slides in the separating direction with respect to the second display unit (30). This state is referred to as a “flat separated state”, and a side view thereof is shown in FIG. Even in this flat separation state, the membrane switch (82) is not pressed by the back surface of the first display section (20), and is in the off state. For this reason, in the flat separation state, the position detecting means (80) gives the control means (60) a relative position signal whose signal value is “0”.

  When the first display portion (20) is lifted so that the first display screen (21) is tilted forward by grasping the distal end side of the first display portion (20) from the flat separated state of FIG. As shown in FIG. 5 (c), the first display screen (21) can be tilted with respect to the second display screen (31). This state is referred to as a “tilt state”. This operation can be performed by holding the second housing (33) with one hand and picking and pulling up the first display section (20) with the thumb and index finger of the other hand.

  In the tilted state, the first display screen (21) is tilted while keeping the second display screen (31) horizontal, so that the first display screen (21) is easily visible. For example, the first display screen ( An electronic device that displays information such as characters on 21), displays a keyboard on the second display screen (31) according to the user's instructions, etc., and has excellent operability by operating the second touch panel (32) (10). Even in this tilted state, the membrane switch (82) is not pressed by the back surface of the first display unit (20) and is in the off state. Therefore, in the tilt state, the position detection means (80) gives a relative position signal having a signal value of “0” to the control means (60).

  As shown in FIG. 6 (a), the first display unit (20) is tilted backward from the tilted state around the connecting portion with the connecting mechanism (40). Further, as shown in FIG. As shown in FIGS. 4 and 6 (c), the first display unit (20) is pushed downward so that the tip of the first display unit (20) approaches the tip of the second display unit (30). The 2nd display part (30) can be made into the folding state which overlapped with the 1st display part (20) being the upper side.

  In the folded state, the first display unit (20) overlaps the second display unit (30), and the second display screen (31) is covered with the first display unit (20). Therefore, in the folded state, only the first display screen (21) is visible, the first touch panel (22) can be operated, and the second touch panel (32) cannot be operated. In this folded state, information is displayed only on the first display screen (21) and the operating state of the first touch panel (22) and the electronic device (10) can be made compact, so it is suitable for non-use state and carrying around. It is. In this folded state, the membrane switch (82) is pressed by the back surface of the first display section (20) and is in the on state. For this reason, in the folded state, the position detection means (80) gives a relative position signal having a signal value of “1” to the control means (60).

  In order to shift from the folded state to the tilted state or the flat approaching state, an operation opposite to the above may be performed.

FIG. 9 is a flowchart showing the flow of display control processing executed by the control means (60) in the present invention.
When the user operates the touch panels (22) and (32), the data receiving unit (72) receives the terrestrial digital broadcast data (step 1). Note that the positional relationship between the first display screen (21) and the second display screen (31) at this time, that is, whether the second display screen (31) is visible or invisible (folded state). Since the determination is made in the steps described later, the determination is not necessary at the start of reception of terrestrial digital broadcast data.

The terrestrial digital broadcast data received by the data receiving unit (72) is transmitted to the data separating unit (74) to separate the moving image data and character data (data broadcast) included in the terrestrial digital broadcast data (steps). 2).
Next, the control means (60) refers to the signal value of the relative position signal output from the position detection means (80) and the presence or absence of the change, and the second display screen (31) is in a state where the second display screen (31) is invisible (signal value “ It is determined whether or not the state has changed from 1 ") to a visible state (" 0 ") (step 3).

  When the determination result of step S3 is “Yes”, the electronic device (10) has shifted from the folded state in which the second display screen (31) is invisible (see FIG. 10) to the visible state, that is, It means that the second display screen (31) has been pulled out to a visible state by a user operation. In this case, the control means (60) displays the moving image data separated from the terrestrial digital broadcast data in step S2 by the data separation unit (74) on the first display screen (21), and separated from the terrestrial digital broadcast data. Character information represented by character data (data broadcasting) is displayed on the second display screen (31) (step 4). The display of each display screen (21) (31) in this state is shown in FIG. As shown in FIG. 11, moving image data and character data (data broadcasting) can be displayed on the first display screen (21) and character data (data broadcasting) on the second display screen (31). In addition, it is understood that the visibility can be improved as much as possible by displaying each of them on a full screen, for example.

  Thereafter, in step S10 following step S4 (or steps 6, 7, and 9 to be described later), the control means (60) gives a display end instruction for receiving terrestrial digital broadcast data via the touch panel (22) (32). If the determination result is “No”, it waits for the reception of the following terrestrial digital broadcast data, receives the terrestrial digital broadcast data, and executes the processes from step S1 again. . Conversely, if the determination result in step S10 is “Yes”, the control means (60) ends the reception and display of the terrestrial digital broadcast data.

  If there is no change in the signal of the position detection means (80) in the above step 3 (“No” in step 3), the state of the display screens (21) and (31) where the user has started viewing the terrestrial digital broadcast data, ie, This means that the second display screen (31) is maintained in a visible or invisible state.

  In this case, the control means (60) cannot visually recognize the second display screen (“Yes” in step 5) or not depending on whether the signal value of the position detection means (80) is “1” or “0”. It is determined whether it is visible (“No” in step 5) (step 5).

  When the second display screen (31) is invisible (“Yes” in step 5), the first display screen (21) displays terrestrial digital broadcast data, that is, video data and character data (data) associated with the video data. Broadcast) are displayed side by side as shown in FIG. 10 (step 6).

  Conversely, if the second display screen (31) is visible (“No” in step 5), whether the second display screen (31) has been invisible since the reception of the terrestrial digital broadcast data is started. It is determined whether or not it is visible by checking whether or not the above-mentioned step 4 has been passed (step 7).

  If “Yes” in step 7, since the second display screen can be visually recognized by the user's operation after starting the reception of the terrestrial digital broadcast data, the video is continuously displayed on the first display screen (21). Data and character data (data broadcast) associated with the moving image data are displayed on the second display screen (31) (step 8).

  On the other hand, if “No” in step 7, it means that the second display screen (31) was visible after the start of reception of the terrestrial digital broadcast data (“No” in step 5). For example, on the basis of the user's operation of the touch panels (22) and (32) and settings, the moving image data and characters are continuously displayed on the entire first display screen (21) and the second display screen (31). Data (data broadcasting) may be displayed side by side (step 9).

  As mentioned above, although one Example of this invention was described, the said Example can also be deform | transformed as follows, for example.

In the above-described embodiment, an application example to display control of the moving image represented by the moving image data included in the terrestrial digital broadcast data received by the data receiving unit (72) and the information representing the data broadcast included in the terrestrial digital broadcast data will be described. is doing. However, the image represented by the image data (moving image data, still image data, image data, etc.) stored in the memory (not shown) of the electronic device (10) and the image data are stored in the memory in association with the image data. Other data such as images and characters may be displayed. In this case, the data receiving unit corresponds to a reader or the like that functions as a reading unit.
Further, when the electronic device (10) can read data recorded on a recording medium such as a CD-ROM or a memory stick, the image or moving image data recorded on the recording medium and the data Data such as other images and characters recorded on the same recording medium may be displayed.

In addition, as the first data and the second data associated with the first data, for example, the first data is a game video, and the second data is character data (data such as a conversation sentence or an explanatory text displayed in the game video). Broadcast).
Furthermore, the conversation data such as chat input by the users associated with the moving image while viewing the moving image with a browser or the like as the first data can be used as the second data.

  The present invention is useful as an electronic device that has two display screens and can display data related to each other on each display screen to improve visibility.
